Definitions
- the invention relates to a bearing device for supporting a movable component, in particular the crankshaft of an internal combustion engine with at least one Component receiving bearings and an oil feed line to each bearing,
- the object of the invention is to provide an improved storage device in which Also particularly sensitive to contamination bearing materials for Use come.
- the filter is not arranged in a common main oil line, but each have their own filter element just before the camp in the respective oil supply line, which branches off from the main oil line and leads to the respective camp.
- Advantageous is a distance of the filter from the bearing in the centimeter range and below. If the design allows it, it is favorable if the output of the filter is less than 5 mm from the bearing, so it is almost directly on the camp. This is the distance, in which potential impurities can occur, disappearingly small, and there are any particles, especially in the assembly of the Engine resulting dirt safely held away from the bearing.
- the invention is particularly suitable for plain bearings, a hard, galvanic or by sputtered coating, which has a small thickness (preferably below 50 microns).
- Such bearings are inexpensive to manufacture, however, they have not been so far due to their sensitivity to dirt used.
- the filter assembly according to the invention can now the pollution problem be solved and also such direct-coated plain bearings with a thin, hard layer can be used reliably.
- the fineness of the filter can be adapted to the respective conditions, for example it is favorable Use filters that retain particles larger than 0.1 mm.
- such a filter can be designed as a so-called gap filter, in which the oil by at least one of the maximum transmitted particle size defining Gap is led.
- a gap filter can be an insert body have, which has V-shaped depressions. The entire insert body is then in a receiving bore is used, which is slightly larger in diameter than the Insert itself. The oil can then flow into a V-shaped recess and over the gap between the outer surface of the insert body and the inner surface of the Overflow receiving bore in an adjacent V-shaped recess, the Camp is open. By the V-shape is achieved that the flow velocity is substantially the same across the gap at all locations.
- split filters are on structurally already known, but have been used only before injection nozzles, to keep impurities out of the fuel.
- Fig. 1 shows a crankshaft 1, which is rotatably mounted in bearings 2.
- enlarged thin and hard coating layer 3 for example, galvanic or by Sputtering is applied.
- the layer has an oil distribution groove 4 in the upper one Bearing half shell on.
- a filter element 5 is now arranged in front of each bearing 3, the Distance from the camp 3 only in the centimeter range and below and conveniently completely disappears, so that the lying between the filter 5 and the bearing 3 Track is as small as possible.
- the gap filter 5, with reference to FIG. 2 even more accurate will be described, is in an enlarged receiving bore 6 of the straight oil feed line 7 used.
- the individual oil feed lines 7 branch from a main oil line 8 and lead from this to the individual camps. So it's not one central oil filter provided, but in each case for the individual warehouse directly in front of this a separate filter 5.
- Fig. 2 shows the insert body 9 of the split filter in different views.
- This Insert body 9 has opposite V-shaped recesses 10 and 11, which in installed state alternately to the main oil line 8 and towards the camp 3 out are open.
- the insert body 9 has a diameter slightly enlarged Zentnerbund 12, which fits snugly against the inner surface of the receiving bore 6.
- the remaining outer surface 13 has a relation to the diameter D1 of the Zentrierbundes 12 reduced diameter D2, bringing them with a certain gap is spaced from the inner surface of the receiving bore 6. The difference from D1 to D2 thus determines the gap size and thus the maximum transmitted particle size.
- the oil flows in through the V-shaped opening to the main oil line recesses 11 and then between the outer surface of the insert body 9 and the inner surface of the receiving bore 6 via the webs 13 of the outer surface in the adjacent V-shaped Recesses 10, which are open to the camp 3 out.
